CHALK-HOLDER.

Specification of Letters Patent. Patented F b 15, 1916 Application filed Apri126, 1915. 'Serial No. 24,170.

To all whom it may concem Be it known that I, WARREN OswELL J ACKSON, a citizen of the United States, residng at Ogden, in the county of VVeber and State of Utah, have invented new and useful Improvements in Chalk-Holders, of which the following is a specification.

This invention is an improved chalk holder for holding and permitting the use of a block of chalk such as is used by mechanics for chalking lines, the object of the invention being to provide an improved device of this character which holds and protects the block of chalk, permits the use ot' the chalk block in chalking lines as well as the necessity of grasping the chalk block in the hand; and which is adjustable as the chalk is used .so as to present new surface of the chalk, from time to time, as the chalk wears,

for chalking the line.

The nvention consists in the Construction, combination 'and arrangement of devices hereinafter described and claimed.

In the accompanying drawings g Figure 1 is a perspective view of a chalk holder constructed in accordance with my invention.

Fig. 2 is alorigitudinal sectional view of the same. Fig. 3 is a transverse sectional view of the same.

My improved chalk holder comprises `a i hollow body 1 of oblong rectangular form and which is square in cross section. The said hollow body is formed of a single piece of sheet metal, preferably brass, which is 'bent to form walls 2, 3 and 4, said walls 3 and 4 being each provided with a portion 5 spaced from and overhanging the wall l and with an outturned flange 6. Said flanges are provided at their outer edges with ratchet teeth 7 and said fianges are spaced apart to form a slot 8 between them, which slot eX- tends from end to end of the body or holder. At one end of the body or holder is an end wall 9 which is spaced therefron so that a slot 10 is formed between said end 9 and the walls 3, l and 5 of the holder or body.

A Vfollower 11 is arranged for sliding movement in the holder and is formed with a flange 12 which bears against the inner side of the slotted wall 5. A guide 13 which is of U-form, cross sectionally, is arranged astride the fianges 6 and across the slot 8, with its ends on the outer sides o' said flanges. A spring dog 14 which engages the ratchet teeth 7 or' the fianges 6 is secured to the guide 13 by a rivet 15 which also operates in the slot 8 and connects the guide to the follower. The follower may be longitudinally moved in the holder toward the end wall 9, and may be detached from the holder by first releasing the spring dog from the ratchet teeth. i

In use, a block of chalk, indicated at A, is placed in the holder and is pressed against the end wall l by the follower, the latter being held in adjusted position by the engagement of the spring dog with the ratchet teeth. This eXposes an end of the chalk block in the slot 10 and permits the placing of a line in said slot and the drawing of the holder along the sane so as to chalk the line. From time to time as the outer end of the chalk block is worn away, the follower must be readjusted to compensate for the wear of the chalk and present a new surface thereof opposite the slot 10 for chalking the line.

My improved chalk holder forms a casng which entirely incloses a block of chalk so that the chalk need not be handled so that the workman avoids the nusance of chalking his fingers when using the chalk. The holder also prevents the chalk from being broken from contact with other objects as when in the tool box and permits the ready use of the block for chalking a line.

Having thus described my invention I claim r 1. A chalk holder comprising a body adapted to hold a block of chalk and provided with a transverse slot near one end to eXpose a portion of the chalk, such body having a longitudinal slot, a fiange at the side of said slot and provided with ratchet teeth, a follower novable longitudinally in the body, a guide for the follower connected thereto and a dog connected to the guide :for engagement with the ratchet teeth.

2. A chalk holder comprising a hollow body formed of a single piece of sheet metal and having an' end wall spaced from one end thereof forming a slot between said end wall and said hollow body, said hollow body having' a longitudnal slot in one side and ratchet toothed fianges on opposte side of said slot, a follower in said hollow body, a guide engagng and slidable on said ratchet toothed flanges and extendng along said longitudnal slot, said guide being connected to the follower, and a dog for engagng the ratchet teeth of the flanges and mounted on said guide. i

In testimony Whereof I affiz my signature in presence of two' witnesses.
